Target release (TGTRLS)

Specifies the release of the operating system on which you intend to use the object being created.

When specifying the target-release value, the format VxRxMx is used to specify the release, where Vx is the version, Rx is the release, and Mx is the modification level. For example, V5R3M0 is version 5, release 3, modification 0.

Valid values depend on the current version, release, and modification level of the operating system, and they change with each new release. You can press F4 while prompting this command parameter to see a list of valid target release values.

*CURRENT
The object is to be used on the release of the operating system currently running on your system. The object can also be used on a system with any subsequent release of the operating system installed.

*INHERIT
The service program is created with inherit storage model. When activated, the service program adopts the storage model of the activation group into which it is activated. An equivalent view is that it inherits the storage model of its caller. When the *INHERIT storage model is selected, *CALLER must be specified for the Activation group (ACTGRP) parameter.

Argument optimization (ARGOPT)

Specifies whether argument optimization (ARGOPT) is to be done during service program creation. Argument optimization is a technique for passing arguments (parameters) to ILE procedures to improve performance of call intensive applications. This option may cause an increase in the amount of time required to create the service program.

*NO
Argument optimization will not be performed during service program creation.
*YES
Argument optimization will be performed during service program creation.
